2393 Precision Welded Steel Tube

DIN 2393 Specification for welded cold drawn steel tubes for automobile, mechanical and general engineering purposes – Specific requirements for cold drawn Welded Steel Tubes. cold drawn seamless tubing possesses a high strength-to-weight ratio and can be processed to provide a combination of desired characteristics: dimensional accuracy; good surface quality; excellent micro-structure uniformity; good machinability; and high tensile properties. It is also suited for such post-treatments as carburizing and heat treating.

2393 Welded Steel Tubes Chemical Component

2393 Welded Steel Tubes Delivery Condition

Cold finished (hard) BK

Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.

Cold finished (soft) BKW

The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming. (e.g. bending, expanding).

Cold finished and stress-relieved BKS

Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.

Annealed GBK

The last cold forming process is followed by annealing in a controlled atmosphere.

Normalized NBK

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.

2393 Welded Steel Tubes Drawing Process

Floating/Drawing process of pulling a metal bar, rod, or wire through the whole of a die to alter its finish, shape, size, and/or mechanical properties. The tube drawing technique reduces the outer diameter, inner diameter, and wall thickness of the tube.

2393 Welded Steel Tubes Manufacturing process

The tubes shall be manufactured from electric welded pre-tubes by cold drawing or other suitable processes. The tubes shall not include welds used for joining lengths of flat rolled strip prior to forming the pre-tube.

2393 Welded Steel Tubes Packaging

Straight lengths of seamless tubing can be individually sleeved in paper or plastic and/or packaged in our unique cardboard spacers to ensure no damage occurs during transit. Coiled seamless tubes are horizontally packed using paper or cardboard separators to prevent tube-to-tube contact. All tubing is packed in either wooden crates lined with wax craft paper, tri-wall clay-coated reinforced cases, or standard cardboard boxes. Plastic end caps that prevent foreign material from getting inside the tubes are also available upon request.
